Air India flight 171 crash simulation suggests dual engine failure
Separate from India’s official investigation, the flight simulator reenactment and turbine deployment indicate a potential technical malfunction in the Boeing 787 crash
Pilots from the airline reenacted the doomed aircraft’s parameters in a flight simulator, including with the landing gear deployed, and the wing flaps retracted, and found those settings alone didn’t cause a crash, according to people familiar with the investigation.
The result, alongside the previous discovery that an emergency-power turbine deployed seconds before impact, has reinforced the focus on a technical failure as one possible cause, said the people, who asked not to be identified discussing non-public deliberations.
Additional clues
Boeing declined to comment and deferred any questions to AAIB, while GE said it cannot comment on an active investigation. The AAIB and Air India did not respond to a request for comment.
